Hi. I was used to draw 2D plot to show distribution of my samples. It was very powerful in small samples. Recently , I handle a lot of type of samples as more 15. so, I want to use more dimention. I was used that I conduct plsda function and draw biplot, such as, p1=plsda(mw, sp) biplot(p1) How can I draw 3D graph with my data?? I don't know exactly numerical value each spot. please,

Hi, I need your help, so I send letter to you. I have a problem about plsr in pls package. I want to show how classfied or related each ohter samples, so I tried to use plsr and biplot.
